let me know. There are other people in Poland who would like to buy it.
While I was looking for informations and talking to people I found two things.
1. Arcade Cabinet Plans You can download plans (in EPS and JPG formats) for over 20 classics machines including Dragon's Lair, Mortal Combat, Galaga and Pac-Man.
2. Extreme Arcade - Automaty Arcade This forum has been set up by a friend of mine. There's a lot of info about building and setting up an arcade cabinet in the Internet but very little in Polish. Not everyone speaks English so this is a place for all Poles who are into arcade machines. Please, spread the news and help the forum to grow up! I hope you find both sites useful.
I'd like to thank Alex for his help. I have some questions and I'll write to you soon.
